You couldn't make entrance requirements "strict" in Canada, the schools would be half empty.
I think you would be shocked to find the number of people who are in post secondary that don't actually have an end goal... beyond graduating.
For example, my brother has BA w/ honors in archeology/classics from UofA and a MA in anthro from Leicester... he's never ever worked a day in a related field or performed any research. So what was his thinking/end goal... I have no idea.
I can tell you I've coddled his socialist ass through life for the last 7 years hiring him over and over again even though he is a lazy piece of shit and gets next to nothing done. He is however, very smart, it's almost as if his end goal was to "be the smartest guy in the room", he likes to use big words that are so uncommon nobody will understand, then when the people to which he is speaking look lost, he gives them the "Oh, you don't understand word X?"
If you've ever read a Christopher Hitchens book.. he basically talks like that atheist fundamentalist lunatic. (I'm an atheist, but that man was just hateful towards religion.)
Not even kidding, if tuition fees ever get eliminated I'll be all over the JD lol Then when I grad I'll contribute nothing to society beyond sucking the financial health out of couples going through divorce
